I'm not sure if you've had previous bans but if you haven't that ban seems excessive, especially for 6 recents. You also should also really only be banned after being given a punishment, as like with this situation, you listened to staff's advice and didn't get any more, then out of nowhere you get banned 4 days later which has to be pretty confusing

He had previous bans, but the most recent one was in July for a week. Meaning he should not have been banned this long regardless.
